Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511694, here are decompositions:

3 + 511691 = 511694
61 + 511633 = 511694
67 + 511627 = 511694
103 + 511591 = 511694
241 + 511453 = 511694
277 + 511417 = 511694
307 + 511387 = 511694
367 + 511327 = 511694

Showing the first eight; more decompositions exist.
